Early BETA aircraft sketch

The BETA team begins development of it’s first eVTOL: AVA-XC

AVA is a 4000lb eVTOL aircraft developed in partnership with United Therapeutics.

BETA moves into its first space at Heritage Aviation

Meet AVA

Designed, built, tested, and flown within 10 months by a handful of engineers, AVA was BETA’s first full-scale proof of concept aircraft. AVA set a record for the heaviest eVTOL aircraft in the world to take flight. This design showed that electric aviation is possible - setting a foundation for the company to build on with future designs.

BETA’s flight training program begins

BETA offers every team member the opportunity to get a pilot’s license. Flight school connects employees to the mission, giving them a common language, a deep understanding for what they are designing, and an important empathy for future operators. Currently, the program has a large team of flight instructors and a fleet of training aircraft — allowing for training opportunities from the Private Pilot’s license all the way up to an ATP.

BETA’s electric aircraft, AVA, starts free hover testing

Flight test operations move to Plattsburgh,
New York

The Plattsburgh International Airport (PBG) is a 15 minute flight from BETA’s R&D facility in Burlington — an ideal location for the company’s flight test headquarters. A decommissioned Air Force base that once housed B-52 bombers, PBG provides ample hangar space, more than three miles of runway, and a supportive community - making it an ideal location for our flight test center.

Ava's teachings inform ALIA

Throughout the AVA program, the BETA team captured learnings about what would ultimately make electric aviation certifiable and commercially viable. This led our team to design and build a simpler, more refined aircraft: ALIA.


Ava's mission is complete — BETA begins design and build of a clean sheet aircraft: ALIA

ALIA was inspired by the Arctic Tern, the farthest known migrating bird in the world. Beta’s engineers used biomimicry to inform many design choices, including ALIA’s long 50-ft wing and large, sweeping tail section.

BETA builds generation 1 electric motor

BETA has taken a strategic approach, partnering with leaders in the aerospace supply chain for critical elements of its aircraft, while internally developing the proprietary electric propulsion system that powers its aircraft.

ALIA’s Iron Bird is built, allowing engineers to test software and complete system integration

BETA installs its first prototype elevated landing pad & pilot station

A crane positions the flight deck on top of BETA’s first custom-built elevated landing pad. Built using recycled shipping containers and designed to operate off the grid, the pad is an option for customers who plan to use ALIA at off airport locations like distribution centers, office buildings, or hospitals. The pad contains modular spaces for crew rest, pilot briefings, energy storage, and more.


"ThunderDome," a full-scale simulator, completed inside BETA's research and development facility

BETA’s first full-scale, enclosed-dome simulator created an invaluable tool for flight test, data collection, and pilot training. All of the company’s test pilots fly full flight profiles inside the simulator before completing the same mission in the manned, full-scale aircraft. Data from simulated flights helps to inform software development in multiple areas. BETA’s simulator runs in part on the popular home-simulation software X-Plane.
